Growth and scintillation properties of a new red-emitting scintillator Rb2HfI6 for the fiber-reading radiation monitor

Popis výsledku v původním jazyce

A new red-emitting halide scintillator ternary rubidium hafnium iodide (Rb2HfI6) was grown by the vertical Bridgman method in a quartz ampoule. Under X-ray irradiation, the Rb2HfI6 has a broad emission band at around 725 nm. The light output and energy resolution were determined to be ca. 40 000 photons/MeV and ca. 7.4% (full width at half-maximum at 662 keV), respectively. The Rb2HfI6 scintillation crystal was used to perform the gamma-ray detection test under high-dose irradiation condition from a 60Co source with an activity of ca. 100 TBq. The dynamic range of the Rb2HfI6 gamma-ray detection with a 20-m optical fiber was evaluated and compared with the previously developed Cs2HfI6 crystal and the conventional deep-red Cr:Al2O3 (ruby) scintillator. The gamma-ray doses from ca. 0.4 to ca. 1 kSv/h were successfully measured using Rb2HfI6 through the 20-m fiber.n
